J. A. LOWE PAPER Filed Dec. 11, 1928 ATTORNEY t INVENTOR fuse 171 fl.L(/we- BY WITNESSES 2% Patented Aug. 11, 1931 UNITED STATES PATENT OFFICE JOSEPH A. LOWE, or rITcHBURo, MASSACHUSETTS, ASSIGNOR To TALULAH PAPER COMPANY, or FITCHBUBG, MAsSAoHUSETTs, A CORPORATION or MAssAcHUsETTS PAPER Application filed December 11, 1928. Serial No. 325,260.

This invention relates to paper and more specifically to paper having an improved identification means normally hid from View but observable when the paper is torn.

A primer object of the invention is therefore to provlde a sheet of paper or a card composed of any desired number of plies, at least one inner ply being of unfinished composition as distinguished from the outer plies and which more freely absorbs moisture than do the outer plies, so that this inner ply is impregnated with a color ingredient which gives a streaky or mottled efi'ect to such inner ply,

and when the sheet or card is torn this streaky or mottled coloring effect is readily observable to indicate the product of the manufacturer.

With these and other objects in view, the

- invention consists in certain novel features of construction and combinatiollig and arrangements ofv arts, which will be ore fully here:

inafter escribed and pointed out in the claims.

In the accompanying drawings- Figure 1 is a fragmentary plan view showing the inner ply of the sheet or card with a colored paste thereon;

Figure 2 is an exaggerated plan view of Figure 1;

Figure 3 is an exaggerated edge view of the completed sheet or card with the outer plies in place;

' Figure 4 is a fragmentary plan view showing the several plies of the sheet or card broken away;

Figure 5 is a fragmentary plan view showing my completed sheet or card with a corner torn ofi to expose the streakv coloring of the inner ply.

It is of course to be understood that the illustrations are more or less diagrammatic, as the machine or apparatus employed for making the paper may be constructed in various wa s, and the drawings are not 1ntended 'to' e illustrative of a method but but has a mottled or merely to illustrate more specifically the invention as it exists in the article itself.

1 represents an inner ply and 2 or 3 outer plies which are Secured to opposite faces ofthe inner ply 1. These plies 1, 2 and 3 are secured together by paste or other suitable adhesive which contains a color, and I have used the reference character 4 in Fig. ures 1 and 2 to indicate the paste as a thickness but which, as a matter of fact, ceases to be a thickness and impregnates the plies and more particularly the inner ply when the sheet or card is formed.

By employing a paste or other adhesive containing a color I have discovered that by reason of the absorption of moisture of the glue by the inner ply 1, which is more porous than the outer plies 2 and 3, the coloring matter in the aste will impregnate the inner ply 1 but will not give a uniform color. In other'words, this color will be mottled or streaked throughout the inner ply and the color will not affect or come through the outer plies 2 and 3.

When a corner of the sheet or card is torn, as indicated in Figure 5, the inner ply 1 will show .the color in streaks or mottled formation and this will prove the .goods of the manufacturer.

#I of course do not wish to limit myself to any particular color nor to an particular medium for making the color but I desire to cover broadly the idea of a sheet of papen or a card in which at least one inner ply 1s impregnated with a color so that said color 1s not a solid color throughout the ply streaky appearance.

I claim;

1. A multi-ply paper comprising outer pl es, an inner ply, and a colored adhesive with which the inner pl is impregnated the adhesive connectin t e outer plies an the color providing a idden identification stratum.

2. A multi-ply paper comprising outer 00 plies, a colored adhesive, and an inner ply more porous than the outer plies being 1mpregnated with said adhesive for the connection of the outer plies but causing an 5 uneven distribution of the color, said inner ply remaining hidden until the paper is torn on a bias cross-sectionally.

3. Paper comprising a pair of plies, and

a colored adhesive to secure the plies in 10 homogeneous sheet form.
